2-part music for high school choir

Suggestions for 2-part music for high school choir. In other words, music in which S & T are doubled and A & B are doubled. Preferably music that is easily accessible to a new choir (think beginning with very little exposure to classical or choral standards).

Hymn to the night, by Brent Pierce. It's SA or TB, I did it with my MS age choir with only two changed boys. I put the young basses on part 1 down the octave, and it worked really well. Both parts could easily be doubled at octaves if you have the voices for that.

There is a 2 part score for schools and young choristers of my new Christmas carol The Age Old Reason for Joy. If you click the link below and I think that it's 9th in the list. It is great fun to sing and carries message in the words. You can also see a video of a performance by a full choir with young children helping out.
